ing tubular fabrics for cases orjackets of fire and other hose. 1

The object of my invention is to produce a' circular loom which will weave a tubular fabric of the nature described in the application of William T. Cole, No. 7 85,847 filed August 21, 1913, for hose fabrics.

The principal characteristic of this fabric is that the weft or'filler strands of the hose are wound or placedhelically about the straight warp strands which are always maintained on the inner side of the weft strands. The weft'or filler strands and the warp strands are united by means of an auxiliary strand which has only the function of a binder, although in weaving the fabric the binder strands are treated in a manner similar to auxiliary warp strands. This. manner of weaving the fabric produces a tubular case orjacket which when used in connection with hose allows very little longitudinal stretch under pressure of the fluid within the hose and also'prevents twisting of the hose under pressure. This arises by, reason of the fact that the main warp strandsware substantially straight while the weft strands are substantially smooth helices or arcs ofcircles and are always located on the same side of'the respective strands, not being sinuously woven in and out between each other as in the case of hose of ordinary interlocking weave. I

For a detailed description of one form of my invention which I at present deem preferable, reference may be had to the following specification and to the accompanying drawings forming a part thereof in which:

Fig. 14 is the weft or filler strands which give the circumferential strength and body to the hose or tubular fabric are wound spirally about the .inner straight warp strands 2. These two sets of strands are bound together by means of the binder strands 3 which pass successively over the warp and filler strands in any suitable way, but preferably in the manner; indicated in Fig. 1, that is, the binder strand is looped over the warp strand between two strands or picks of the filler, then passes over two of the filler strands and again between two picks of the filler in the opposite direction, this being repeated during the entire length of the warp strands, and the adjacent warp strands having the loops of'the binder strands arranged alternately with those about the other warp strands.

The main principleof the operation of the machine is .most clearly illustrated in Fig. .3 in which it will be seen that the warp strands 2 pass around a small wheel 4 at the lower end of the downwardly projecting supporting rods 5. From this wheel. the warp strands pass upward, as indicated in Fig. 6. The binder strands 3 are threaded through the ends of vertical reciprocating heddles 6, there being two sets of heddles for each radial segment of the machine, which operate alternately to produce the alternate loopings of the binder strands about the warp strands. In Fig, 3 two of these heddles are shown in the raised position and two in the lowest position, the upper ones being indicated by the numeral 6 .and the lower ones by the numeral 6'. The looping 'action of the binder strands about the warp strands is produced by shifting the binder strands around the lower ends of the vertical rods 5 which contain the warp strands. In Fig. 3 the binder strands which pass through the heddles 6 have just passed said ends of the vertical rods and are starting on their upward movement, the loop having just been made.

The switches or guides 7 are what produce the requisite motion to the binder strands about the warp strands passing through the ends' of the rods 5. In Fig. 3 it will be seen thatthese switches are indicated as inclined toward the left. The downward motion of the heddles carrying the binder strands has caused the binder strands to pass between the switches 7 and the rods 5 at the point indicated by the letter a. By a further motion, the binder strand is slightly deflected until the end of the rod 5 is reached, at which point the tension of thestrandcauses it to spring around the end of the supporttoward the right, it being unrestrained in. that direction, and the next upward motion of the strand causes the support 5. The heddle then continues its upward motion until the position 6 is reached at which point the shuttle carrying the filler strand passes between the binder strands and the warp strands. lowed by the beater, as indicated in Fig. at. This comprises the essential operation of the machine, the details of which will now be described.

The machine as a whole is of the general type of that shown in. the patent to Stowe, No. 416,085fdated Feb. 10, 1891, the shuttle, however, being driven by a pushing wheel similar to that illustrated in the patent to De Laski, 502,231, dated July 25, 1893.

. Referring to Fig. 6, the numeral '8 indi-l cates a base upon which the main parts of' the machine are mounted. At the center of this is a vertical stationary spindle 9 upon the upper end of'which is placed the forminghead 10. Adjacent the lower end of the spindle 9 a gear 11 is rotatively mounted and thisis-pinned or otherwise keyed to the two cams12 and 13, the upper one of which carries a sleeve 14 to which is fixed a disk 15 carrying the shuttle driving mechanism. .The gear 11 meshes with the pinion 16 fixed to the upper end of a shaft 17 in the bearing 18' projecting downward from the base 8. The lower end of the shaft 17 carries a beveled gear 19 which meshes with a corresponding beveled pinion 20 fixed to the main driving shaft 21. The gear 22 fixed to the spindle 9 adjacent the upper end meshes with a corresponding beveled pinion 23 which drives the push wheel 24: by means of a shaft 25 carried 1n the bearing 26 mount ed on the carrier 15. The posts 27 support the circular frame 28 on which are mounted the shuttles 29 and the guides for the heddles 6 and 6, as well as the other parts for directing the warp threads 2 to the proper weavingposition about the forming head 10.

Referring to Figs. 6, 8, 10 and 11, it will be seen that the shuttles comprise first, an annular segmental support 30 which is guided in the frame 28 by having its edges working in grooves 31 formed on the inner horizontal sides 'of the recesses 32. These recesses are formed in the vertical radial platens 33, so that the shuttle support .30 is always carried by at least 4 of the platens. Fixed to the segmental support 30 are two vertical arms 34 whose upper ends form \bearings for the spool or bobbin 35 on which the weft or filler strands are wound (Fig. 8). I

Also projecting from the segmental support 30 is stud 36 upon which is rotatably mounted a toothed wheel 37. The notches in this wheel 37 are for the purpose of allowing the warp strands to pass between the driving wheel 24 and the toothed wheel 3.7 Without abrasion from being pinched between the two wheels.

same to pass along the right hand side of the I This is immediately fol- By referring to Fig. it will be seen'that as the toothed wheel 37 advances under pressure of the wheel 24,'the Warp strands 2 are deflected downward by being caught in the notches of the wheel 37 and as the wheel passes are then forced slightly .upward over the highest point of the driving wheel 24 until they are again allowed to assume their normal position under the tension of the strands.

Also attached to the segmental shuttle support is a bowed-wire dividing member 38 which raises the binder strands 3a sufficient distance toallow thev parts of the shuttle to pass beneath without contacting therewith. Upon two carriers 39 fixed to the shuttle support 30 are pivotally mounted two ends of an approximately U-shaped frame 40 which forms a support for the weft tension devices, the binder spacing device and the beater or packer. Upon this frame 40is also supported another bow separator 41 which serves in addition to the separator 38 to enable the parts of the shuttle to pass beneath binder strands 3. This is also aided by a third Separating bar 42 which is located parallel and adjacent to the spool 35. Thespacer 43 is rotatably mounted upon a stud 44 carried by the frame 40.

The upper end of this stud carries two eyes 45 through which the filler strand 1 passes directly from the spool or bobbin 35. The filler strand then passes through two eyes 46 carried on the base of a stud 47 (Fig. 11)

40 I the disks and 51. The filler strand then on which is mounted a grooved wheel 48. The strand then passes between two disks 49 which are forced toward each other by means of the springs 50 and 51 mounted on the horizontal bolt 52, the nut'of which may be turned to adJust the pressure between passes once around the grooved wheel 48, the grooved wheel 53, and a grooved disk 54 fixed to the" spacer 43; thence it passes to the weaving point and. is forced home. by

the packer or spacer 55 which consists of an arm screwed to the frame 40, as indicated. The grooved wheel 53 is mounted on the lever 56, the inner end of which is pivoted to a projection on the frame 40, and the outer end of which is pivotally connected with the screw-threaded bar 57 which passes through the lug 58 on the frame 40.

- Between the nut 59 and the lug 58 is a compression spring 60 which gives the requisite pull according to the tension obtained by the friction disks 49.. Between the arms 34 and passing through holes therein'is a rod 61 upon the middle of which is mounted an arm 62 having a friction pad 63'attached to its outer end. This bears upon the filler strand on the spool or bobbin 35 to give the requisite friction and prevents the strand from unwinding too rapidly, the requisite pressure being provided by a coiled spring 64 on the rod 61. This completes the bobbin and its attached parts. There being two of these bobbins, two filler strands are always wound side by side about the warp strands at the weaving point.-

These bobbins are kept in correct relative position by the push or driving wheels 24 mounted on the carrier 15, the latter being rotated at approximately the same circumferential speed that the bobbins advance, by means of the gears 22 and 23 (Fig.6)

As above referred to, the warp strands 3 pass small grooved wheels 4 (Fig. 6) mounted on the lower ends of the supporting rods 5 having previously passed over the grooved wheels 65 mounted upon the upper corner of the frame 28 to which theyare delivered from a supporting ring 66 carried on the bracket 67 attached to the frame 28. The binder strands 3 also pass through the ring 66 and thence to the heddles '6 and 6:

which reciprocate through holes in the hori-- zontal ring 68 attached to the lower edges of the bracket 67. This reciprocating motion is produced by means of the levers 69 and 69 fulcrumed on the. supports 70. The inner ends of the levers 69 and 69 engage cam tracks or grooves in the horizontal cams '12 and 13, respectively. The outer ends of the levers 69 and 69- are connected with the heddles through the connecting bars 71 and ofthe heddles and the action of the switches referred to. This action will be clearly seen by referring to Figs. 7 9, 12 and 13.

In Fig. 7 it will be seen that the switches 7 are mounted on brackets 73 carried on the lower supporting ring 28' of the frame 28 and between the platens 33. One switch is located opposite the lower 'end of each warp strand support 5 and there being twelve of these corresponding to the two sets of heddles 6 and 6 carried on the yokes 72 and 72 comprised in one segmental section of the machine between two platens, there must he therefore twelve stitches. This will be/ most clearly appreciated by referring to'Fig. .9. Each set of switches-is pivoted to a grooved yoke 74 (Figs. 3 and 15) fixed on the upper end of an arm 75 attached to a plate 76 (Fig. 16) by means of the screw and slot connection 77. A connecting bar 78 ispivoted to the plate 76, the latter also being pivoted to the lever 79 fulcrumed on the supporting ring 28. This lever is provided with a series of holes adjacent one end, indicated by the numeral '80, to allow adjusting" of the angle of inclination of. the switches '7 in conjunction with the screw and slot connection in the plate 76. The inner end of the lever 79 is provided with a grooved cam follower 81, the groove of which is adapted to receive the ribs 82 and 83 of a double cam track mounted on the lower side of the carrier 15 for the shuttle one complete revolution of the shuttle driving mechanism and during the passage of the two shuttles and inclined in the oppo-' site direction during the next revolution of the shuttle driving mechanism and the succeeding' passages of the two shuttles.

It should be noted that during the passage of the shuttles between the warp strands 2 and the binder strands 3, both sets of the binder strands are in the raised po-' sition and the looping action of the binder strands about the warp strands takes place at an angle of 90 degrees to the position of the shuttles. This will be made evident by comparing Fig. 8 with Fig. 9 and Fig. 6 with Fig. 7.

Referring particularly to Fig. 9 it will be seen that the segmental group A of strands is indicated as having six of the binder strands 3, which pass through the heddles 6, located at the righthand side of the warp strand supports 5, the switches 7 being in .the position shown in Fig. 3 or Fig. 13,

the heddles 6 being required to move down ward before passing strands 3 toward the left around the ends of the'warp supports 5. The segmental group B of strands in Fig. 9 includes the set of binder strands 3 which pass through the heddles 6 and which are in contact with the left hand side of the warp supports 5 and requires the heddles to move downward before passing the corresponding strands 3 around the end of the warp supports 5 by a motion toward the right through the guidance of the switches in the position shown in Fig. 12.

The parts thus far described are only those which are necessary to be understood in connection with the new features of the machine which produce the particular kind of weave described. It will be understood that other'parts may be supplied by those" .slgilled, in the art, such as, for instance, a

suitable let-off for the yarn and a suitable. take-up for the woven fabric. ,It will also be understood that the yarn for the warp and binder strands is carried on spools or bobbins supported in suitable frames or racks at some point adjacent the machine from which the yarn extends without interfering with free access to the parts of the machine during its operation.

The operation of he machine may be described briefly as follows, the description covering one complete cycle of operation of a segment or section of heddles and switches or during the period the two shuttles make two complete revolutions, thereby laying in four picks or strands of the filler or'weft.

Starting with the parts in the position indi- 'cated in Fig. 6, both of the heddles '6 and 6 are raised and the shuttles are passing between the warp strands 2 and'the binder strands 3 so that a strand is being laid in at each diametrically opposite point in the circumfe ence of the forming head 10.

When the shuttles have rotated to an angle. somewhat less than 90 degrees, the heddles 6 on the left hand side of the machine. (Fig. 7) have been lowered previous to the next passage of the following shuttle. This is indicated in the segmental group of strands in section B of Fig. 9 and also in Fig. 12. The switches being inclined toward the left, the moving binder strands are deflected toward the right'around the ends of the warp supports 5 and on the upward movement of the heddles 6 are placed at the right hand side of the said supports. Upon a completion of an upward movement of the heddles 6" the next succeeding shuttle passes between the warp strands and the binder strands and is immediately followed by the second shuttle without any change in the heddles 6, thereby causing the particular strands passing through the heddles 6 to be looped over twp of the filler strands, but between the passage of the first shuttle and the second "shuttle,

the other set of binder strands carried by the heddles 6 have been looped under the warp strands, thereby alternating the loops of that set with the loops of the first set so that the said loops are-between the two filler strandsover which the binder strands in the first set are looped.- In themeanti-me, however,

the switches 7 have been changed since sition shown in Fig. 13, and before the first shuttle reaches the. same set of strands on the .second round, the heddles 6 are again of the warp ,supportsfi by reason of the inlowered andtransferred to the opposite side clination of the switches, as shown in Fig. 5. One shuttle then passes between the warp strands and the binder strands after which the second set of hedd les is lowered to transfer the corresponding binder. strands to the opposite side of the corresponding warp supports without changing the switches. The.

second shuttlethen passes and the parts return to the position indicated in Fig. 6. The actions at'all segments of the machine are, of course, duplicates of each other; These actions resultv in the .weaving of the fabric illustrated in Figs. 1, 2 and. 3.- However, this weaving may be varied according to re.

quire-ments by rearranging the action of the different parts, as will be apparent to one skilled in the art. For instance,-a single. shuttle may be used instead. of twoshuttles, in which case the two sets ofheddleswould remain in position during two complete revolutions of the shuttle and the switches would be changed only between two complete revolutions of the shuttle, although each set of heddles wouldhave to be lowered and raised alternately. This. would produce the same weave but, of course, at

only one-half the rate possible with two shuttles unless the speed of themachine be increased so that the single shuttle made twice the number of revolutions per minute.

- Other changes may be made by those skilled passages of the shuttles.

Having thus described this form of my,

in the art in order to produce different styles of weaving, retaining, however, the essen-v tialfea-ture of my improvement which consists in looping the binder strands about sta.-. tionary warp strands between one or more invention, I do not wish to be understood as beinglim-ited to the details of form and arrangement ofrp-arts herein set forth, for,

various changes may be made in such details without changing the essential features of the machine, as I consider myself en-,
